Hi all,
We got this hooked up and it is running but it is very low power. We tried a different motor on it and got the same result. It is running at far less than half the speed we expect and that is on the rack so not under load. Do you think this could this still be the result of the phase wires or hall sensor wires being incorrectly hooked up?
